When God afflicts His children in correction, He has specific aims. His purpose in the correction is to purge His children of their sin and bring them to a state of greater happiness and holiness of life. It is for their good! To the child of God, every affliction is a correction. God never sends random or unnecessary correction. So, every affliction that comes to the believer is working a particular good in his life, all according to the Father’s purposes.
Now, when God afflicts the sinner, He does so with a vengeance. God’s justice demands payment and cries out against the sinner. All His debts will be paid in full.
Psalm 75:8 “For in the hand of the LORD there is a cup with foaming wine, well mixed, and he pours out from it, and all the wicked of the earth shall drain it down to the dregs.”
God punishes the wicked according to His wrath, but this is never the case with His children. Christ has suffered all for the people of God. All our punishment was laid on Him and now we are wonderfully corrected and kept in the narrow way!
